Saturn and Four Moons
Inspired by the seeing at Brentwood Elementary (School Observing Program) I set up when I got home. The views of Saturn were amazing especially with the moon Titan so close to the planet. I knew imaging wasn't going to be easy given I was using the refractor with the 5x Powermate. The high magnifications required to get a decent image size makes for a dim object for video. However I was glad I tried as it is possible to do with a 4" refractor.When I stretched the image I could also make out some other moons.To make them obvious I used the Solarize filter in Photoshop. There is a moon missing,Mimas but I could see it was just on the boundary of perception. Mag 13 for the refractor was the limit given the fast exposure of the video frames.
